Keypad assembly and electronic device using the same

A keypad assembly comprising:

• a support member;
• a fixing bracket fixed to the support member;
• a key switch fixed on the support member and comprising a triggering portion;
• a keycap located opposite to the triggering portion;
• and
• a resilient member comprising a rotation portion and a resilient support portion connected to the rotation portion, wherein the rotation portion and the resilient support portion are substantially U-shaped, opposite ends of the rotation portion are connected to opposite ends of the resilient support portion respectively, such that the rotation portion and the resilient support portion cooperatively form a looped structure, the rotation portion is rotatably connected to the keycap and the support member, the resilient support portion is capable of elastically deforming, and is elastically deformed the keycap biases the triggering portion.

An electronic device comprising:

• a housing defining a mounting port;
• a keypad assembly located on the housing, the keypad assembly comprising:
• a support member fixed to the housing;
• a key switch fixed on the support member and comprising a triggering portion;
• a keycap comprising a limiting portion located opposite to the triggering portion and partially received in the mounting port;
• and
• a resilient member comprising a rotation portion and a resilient support portion connected to the rotation portion, wherein the rotation portion is rotatably connected to the keycap and the support member;
• the resilient support portion is elastically deformed by resisting the support member to make the limiting portion keep resisting against the triggering portion when the key switch is not triggered, and provides an elastic restoring force to the rotation portion.
